My comment:

The SetPrinter function is used for this task. It makes no selection, but deletes all jobs it can find. For deleting a single job use the SetJob function.

For Windows NT/2000/XP you must open the printer with a certain level of access: PRINTER_ACCESS_ADMINISTER. Otherwise the SetPrinter function will return error code 5 (ERROR_ACCESS_DENIED).

* * *
Having sufficient rights, a user can manually stop the spooler, delete files from the spooler directory (c:\windows\system32\spool\printers), and then re-start the spooler:

NET STOP spooler
REM DEL *.*
NET START spooler
